I've researched the FL5 spare conundrum as best I can and found the following.
The supplied sealant has an expiration date, is reportedly messy, and the pump is puny.
My CTR came without a jack or lug wrench.
Kits for older Acura RLs reportedly fit the 2023 CTR.
Kits for the 2019 CTRs have been reported to fit the 2023 CTR.
Kits from ModernSpare are advertised to fit the 2023 CTR. Personal experience says not, but was fully refunded.
The smaller spares should not be used to replace a flat front tire as vehicle mechanics may be harmed.
Some European models and early prototypes reportedly come with spare kits.
"Dallman" has/shows the best documentation for a spare kit. Kudos to Don.
My dealer said a kit for the FL5 was "in development."
No matter which "donut-sized" spare is used, a front blowout necessitates two, wheel changes.
A spare kit will not fit completely under the cargo area's floor board without modifications.
My solution was to purchase an OEM full-size wheel and tire and to secure it in the cargo area.
It adds weight (along with a jack and collapsable wrench).
It takes up about two-thirds of the cargo area, but is easy to remove when needed and deck shelves are available on Amazon.
